T. Claim.

This invention relates to tool handles and more particularly to rotatable handles and knobs of the type commonly used on auger braces.

One of the objectsof this invention is to provide a knob for an auger brace which is rotatable virtually without friction while requir'mg a minimum of lubrication.

Another object is to provide a handle for an auger brace having the above stated advantages.

A further object is to make it possible to use novel materials in the manufacture of the outer portions of such knobs and handles.

A still further object is to provide novel and advantageous means for mounting the name and/or trade-mark of the manufacturer in such tools.

Other objects will appear from what follows.

One embodiment of the invention will now be described, as a non-limiting example, in connection with the accompanying drawing in which:

Fig. 1 is a longitudinal section of the head and handle portions of an auger brace constructed according to this invention;

Fig. 2 is an elevation of a brace head showing a way of mounting manufacturers name and trade-mark; and

Fig. 3 is an elevation showing the reverse side of Fig. 2.

It is one of the purposes of this invention to make possible the use of ornamental materials, such as the well-known transparent colorahle condensation resins or other moldable plastics,

in the manufacture of frictionless rotating tool parts. Accordingly, head knob 6 and handle 1 should be visualized in the drawing as substantially transparent. Quill 8 is provided interiorly with an Oilite bronze bearing 9 (as shown in Fig. l). Quill 8 is held in place by U-shaped key It] fitting in lateral slots I l in main or crank shaft [2. At its other end quill 8 rides against washer I3 and ball bearings Hi carried in flanged collar I 5. Quill 8 is provided with annular shoulder I6 against which rests metal shell or base plate l'l, securely fastened thereto by friction, solder or other suitable means. Knob 6 is secured to the rest of the head by screwing over threaded portion N3 of quill 8 and is bolted to base plate ll by means of screws It in screw holes 20. This construction is extremely simple and requires no further lubrication than a relatively slight amount applied when the .tool is initially assembled.

Head knob 6, as shown in Fig. 1, is provided with a tapped hollow central recess 2i and a pair of concentric grooves 22 and 23 cut into but not completely through the head from the bottom or back. Obviously, the number of grooves may vary from that shown in the drawing. Since the material of which head 6 is made is preferably transparent, recess 2! and grooves 22 and 23 (C1. MES-81) are preferably utilized according to this invention for the displaying of manufacturers name, his trade-mark or other desirable indicia, as shown in Fig. 2. A convenient way of applying such insignia is by gluing, or otherwise securing within the groove, 21. piece of paper on which are mounted the desired words. Obviously, this feature of the invention is capable of very varied application, but the described construction has the advantages of being initially extremely simple and at the same time as permanent as is the life of the tool itself.

Handle l is preferably made of the same material as head t is interiorly provided at each end with Oilite bronze bearings 2Q- for easy rotation on shaft l2, thus giving this portion of the tool the same advantages as described in connection with the head portion. Handle 1 is held in place in conventional fashion by cooperating collars 25, soldered or otherwise secured to shaft 52.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claim is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

A brace handle comprising a quill, means to mount said quill rotatably on the brace, said quill having a threaded outer portion and an inner portion of larger diameter forming a shoulder between said portions, an annular backing plate mounted on said quill and rigidly secured against said shoulder, a knob of transparent, colorable, plastic material slightly larger in diameter than said plate and having a tapped hole in one side which is threaded onto said threaded portion of said quill, said knob having a rim around said tapped hole adapted to bear against said plate, the outer edge of said plate being turned towards said knob so as to engage said knob adjacent the circumference thereof, leaving an annular space between said plate and. knob intermediate said rim and the circumference of said knob, means acting across the space between said knob and plate to secure said plate to said knob, said knob having a plurality of annular recesses in the side adjacent said plate, and indicia in at least one of said recesses visible through said knob.
